Dear Lamborghinisti,
Hi Raymond.
For your seal, the black 3M weather / molding seal is the way to go.
First, clean both the painted surface and rubber surface with 3M wax/tar remover ( blue spray can - walmart )
I'm sure you can see a line where the rubber seal sat on the painted surface. Lay down some masking tape 1/16" below the seated surface. ( so glue is slightly below the rubber, not flush, so it won't ooze out.
After masking tape, use 3M wax remover on cloth and rub surfaces. Apply black 3M sealant in a thin single layer on both sides. Wait for slight surface tack and press down. ( You get one chance to do it right or you will have to start over )
When applying glue, spread fast with finger. If you wait or do it too slowly, the glue will start to "skin"
Good luck....easy job...just take your time.
